    Hi there,

    use nio2-elf-objcopy

    you will probably want something like:

    nios2-elf-objcopy -O binary input_file.elf output_file.bin

    Regards,

    hello cybdenw

    I used

    nios2-elf-objcopy -O binary input_file.elf output_file.bin

    the input file .elf :409KB but the output_file.bin is 9M

    it seems wrong

    i use the following script, it converts first

    from .elf -> .flash and then from .flash(srec) -> .bin

    you have to adjust some settings in the script (addresses)

    SCRIPT: elf2bin.sh

    use: elf2bin <ELFFILE> <BINFILE>

    # ################################################################################ CONVERT NIOS ELF-FILE TO BINARY FILE

    SRC_FILE=$1

    SRC_FILENAME=${SRC_FILE##*/} # returns the file name with the all directories removed:

    SRC_FILENAME_NOEXT=${SRC_FILENAME%%.*} # returns the path with all extensions removed:

    SRC_FILEBASE=${SRC_FILE%.*} # remove last extension

    # echo "SRC_FILENAME :"$SRC_FILENAME# echo "SRC_FILENAME_NOEXT :"$SRC_FILENAME_NOEXT# echo "SRC_FILEBASE :"$SRC_FILEBASE

    DST_FILE=$2

    echo ----------------------------------------------------------------------------

    echo "CONVERT ELF FILE : "$SRC_FILE

    echo "to BINARY FILE : "$DST_FILE

    # ################################################################################ COPY FILE# cp ../1DVI02_SOFTWARE/$FILE/DEBUG/$FILE.elf $FILE.elf -v

    # ################################################################################ CONVERT ELF->FLASH FILE

    # ELF2FLASH .ELF INPUT FILE

    ELF_FILE=$SRC_FILEBASE.elf

    # ELF2FLASH .FLASH OUTPUT FILE

    FLASH_FILE=$SRC_FILENAME_NOEXT.flash

    BINARY_FILE=$DST_FILE

    # ##################### SETTINGS FOR ELF2FLASH CONVERTER

    FLASHBASE=0x00000000

    FLASHEND=0x007FFFFF

    RESETADDRESS=0x00000000

    FLASH_ID=U1

    # BOOTLOADER

    BOOTLOADER=boot_loader_cfi.srec

    echo ----------------------------------------------------------------------------

    echo "CONVERT FILE : "$ELF_FILE

    echo "to : "$FLASH_FILE

    echo "BOOTLOADER : "$BOOTLOADER

    echo "FLASH ID : "$FLASH_ID

    echo "FLASH BASE ADD : "$FLASHBASE

    echo "FLASH END ADD : "$FLASHEND

    echo "RESET ADD : "$RESETADDRESS

    echo ----------------------------------------------------------------------------

    elf2flash --input=$ELF_FILE --output=$FLASH_FILE --base=$FLASHBASE --end=$FLASHEND --boot=$BOOTLOADER --reset=$RESETADDRESS --flash=$FLASH_ID --verbose

    if [ $? != 0 ]

    then

    echo "--- !!! ERROR !!! !!! ERROR !!! !!! ERROR !!! !!! ERROR !!! ---"

    exit -1

    fi

    # ################################################################################ CONVERT FLASH FILE->BINARY FILE

    echo "CONVERT FILE : "$FLASH_FILE

    echo "to : "$BINARY_FILE

    nios2-elf-objcopy -I srec -O binary $FLASH_FILE $BINARY_FILE -v

    rm -v $FLASH_FILE

    ECHO "PRESS ANY KEY"
